OIL-LAMP BURNER.

Specification of Letters Patent.

Patented June 1, 1915...

Application filed February 1, 1915. Serial No. 5,479.

To all whom it may concern:

Be it known that I, JOHN PHILEMON TRUESDELL, a citizen of the United States, residing at Tiverton, in the county of New port and State of Rhode Island, have invented a new and useful Improvement in Oil-Lamp Burners, of which the following is a specification.

My invention has reference to an improvement in oil lamps and more particularly to an improvement in the burner of oil lamps of the flat wick type.

In the usual construction of flat wick oil lamp burners, the combustion is imperfect thereby producing a flame having a pronounced yellow color with a low light value. This imperfect combustion is also insanitary as it causes the lamp to smoke easily and give off offensive odors.

'The object of my invention is to provide a flat wick oil lamp burner with means whereby a brilliant flame is produced, the flame has a largely increasedlight value, smoke and odor are practically eliminated, blacking of the chimney reduced to a minimum, oil consumption reduced, longer life to the wick and less liability of explosion.

My invention consists in the peculiar and novel construction of means applied to an oil lamp burner of the flat wick variety, said means consisting principally of a thin flat metal plate having a plurality of cavities in the bottom of which is an aperture, said plate lying flat against the fiat side of the wick tube, and other details of construction, as will be more fully set forth hereinafter, andclaimed.

Figure 1, is a side View of a common oil lamp burner having a flat wick tube provided with my device and showing the burner partly in section. Fig. 2 is an enlarged outer face view of the device removed from the burner. Fig. 3, is an enlarged end view of the device. Fig. 4 is an enlarged top view of the device showing the upper end of the wick tube in broken lines, and Fig. 5 is a still further enlarged detail sectional view through one of the cavities taken on line 5. 5. of Fig. 2.

In the drawing, 7 indicates a well known form of oil lamp burner and 8 my device.

The burner 7 may be of any well known construction having the usual flat wick tube 9 for a flat wick 10, and the usual means 11 for raising and lowering the wick. As the burner forms no part of my invention a detailed description of its construction is unnecessary.

My device 8 consists of a flat rectangular shaped thin metal plate 12, constructed to have a plurality of cavities 13. 13, preferably cone-shaped, each cavity having a comparatively large mouth 14 opening out of the inner face of the plate and a small aperture 15 in the bottom of each cavity. An arm 16 on each end of the plate is shaped to clamp the plate to the wick tube and legs 17. 17' on the lower edge of the plate rests on the burner base and holds the plate in the required position. The plate 12 may be adjusted for height on the wick tube 9, by bending the legs 17. 17 as shown in Figs. 2 and 3 so as'to lengthen or shorten the legs. The plate 12 is secured in place flat against the flat side of the wick tube with the open mouths 14. 14 of the cavities 13. 13 toward the wick tube 9 and with approximately one-third of the upper portion 7 above the top of the wick tube 9, as shown in Fig. 1. The plate is held from end-wise movement on the wick tube by an asbestos filling 18. 18 in the pockets formed by the plate 12, arms 16. 16, and the round edges of the wick tube 9.

The operation is as follows: The wick 10 is turned up by the usual means 11., and lighted. The lamp flame heats the air in the cavities 13. 13. The air in the cavities expanding rushes out of the cavities through the large mouths 14. 14 into the flame and simultaneously cold air enters the cavities through the small apertures 15. 15 in the bottom of the cavities. as indicated by the arrows in Fig. 5. Thereafter or as long as the lamp is burning the fiame is provided with a constant supply of hot air rich with oxygen. By the peculiar and novel construction of the plate 12, the number, size and proportion of the cavities 13. 13, the size of the mouth 14 in proportion to the size of the aperture 15 in the bottom of the cavities, which are preferably four to one, are such that perfect combustion is obtained with the following results: a brilliant flame having a greatly increased light value, no smoke or odor, no blacking of the chimney, reduction in oil consumption, no liability of explosion and longer life to the Wick.

It is evident that the plate 12 with its cavities 13. 13, could form a part of the burner and other details of construction such as the shape of the cavities could be varied Within the scope of the appended claims.

Having thus described my invention I claim:

1. An oil lamp burner of the fiat Wick type having a flat plate positioned flat against the flat side of the Wick tube and extending above the tube a predetermined distance, said plate having a plurality of cone-shaped cavities, each cavity having a mouthtoward the Wick tube and an aperture in its bottom, said mouth being approximately four times larger than the aperture.

2. In an oil lamp burner of the flat Wick type, a plate fiat against the flat side of the Wick tube and extending a predetermined distance above the Wick tube, said plate haw ing a plurality of cavities, each cavity having a mouth toward the Wick tube and an aperture in its bottom, and means for detachably securing the plate to the burner.

3. In an oil lamp 'burner of the flat Wicks type, a rectangular shaped plate against. the flat side of the Wick tube and extending a predetermined distance above the Wick tube, said plate having a plurality of cone-shaped cavities, each cavity having a comparatively large mouth facing the Wick tube and an aperture in its bottom, and means for detachably securing the plate to the Wick tube.

4:. In a fiat wick oil lamp burner, arrectangular shaped plate flat against the flat side of the Wick tube and extending a predetermined distance above the Wick tube said plate having a plurality of cone-shaped cavities, each cavity having a comparatively large mouth facing the Wick and an aperture in its bottom, the center of the aperture being on-a line With the center of the mouth, means for adjusting the plate for height and means for detachably securing the plate to the Wick tube.

5, An oil lamp burner of the flat Wick type having a flat plate on the flat side of the Wick tube, said plate having a plurality of cavities, each cavity having a comparatively large mouth facingthe Wick tube and a central aperture initsbottom, said aperture being less than half the size of the mouth of the cavity. r

6. An oil lamp burner of the flat Wick type having a flat plate on the flat side of JOHN PHILEMON TRUESDELL,
